Lay it to rest. There is no way you can win this dissuasion, and frankly I don't come to this forum to read about this silly discussions.

If you want my short answer: I knew about the strengths (!) and weaknesses of the MFT format.

If you want the long answer: I am a salesperson, and by definition 90% of the people don't have a clue what they are buying into. More so if they are C*n*n or N$k$n users. Because it takes courage to buy into a system that is less popular, you will find more informed people in the FT/MFT world. That said: there is no such thing as full frame, because by the very definition of it, there is no lens that I know of that uses the whole frame of the sensor (quite rightly so, because it would have severe vignetting.) Probably the least informed people buy 135mm format anyway, because they have the money, don't know what the are buying, but because they can and because they want to show off they buy a 135mm format camera. Sth like most people who buy an iPhone: they don't know sh*t what it can do, but they buy it to stand out in the crowd...
